To a/ZZ whom, itmotyco'ncerb: I. l

Be it known that I,J EAN SCHOENNER, man ufacturer, a residentlof Nuremberg,vBavaria, German Empire, have AinventedA certain new and useful Improvements inlToy Phonolar View cording to requirements, sometimes for re-.

ceiving or recording and sometimes for delivering or reproducing the conversation, a section of the resonance or sond tube, on the under side of which the diaphragm, together with the diaphragm-pin, vis iixed, is movably arranged and may be turned about one hundred and eighty degrees. diaphragm-pin is brought into two dierent positions in such a way that it may serve as a receiving or recording pin in one positionv and as a delivering or reproducing pin in the opposite position when turned about one hundred and eighty degrees. By giving the diaphragm and pin a suitable form and angular.

arrangement relative to the revoluble section of the sound-tube the result is attained that the diaphragm-pin, as will be hereinafter eX- plained, assumes' each time the necessary position relative to the phonograph-cylinder as is requisite on the one hand for the correct recording and on the other hand for the clear reprc-iuction of the speech. Y

The arrangement is shown in the accompanying drawings, in which- Figure l is a side elevation, and Fig. 2 an end view, of the toy as a whole. Fig. 3 is an enlarged partly-sectional View of the soundregulating chamber. Fig. 4 is an enlarged detail rview showing the diaphragm and piny in positionior reproducing. Fig. 5 is a simiingthe diaphragm shifted into y tioiifor recording. Fig. 6 is an enproper larged'` etail'view of the bifurcated or doublepointed diaphragm-pin.

:istmounted at both endsl in bearings l hand `has one end screw-threaded to engage an internal threadin one of the bearings, by means 'of which the phonograph-cylinder is slowly displaced in-an axialdirection upon the spindle being turned by ahhandle yk. 1 The sound or resonanceltube1 serves for receiving and giving off the speech, and the speaking appliancesare `fixed on a frameg, and during the receptionof speech .the sound travels through v the sou rid-tubes fr r r2 r3 r4 to the diaphragmhox' (nt and sets'in. vibration the diaphragm, which is arranged on the under side of said box. On this diaphragm there is fixed a diaphragm-pin s, the point of which encounters the upper surface of the phonograph-cylinder, and thereby, according to the vibrations of the diaphragm, certain impressions on the cylin'der are made in the ordinary way.

The special-arrangement which renders it possible to utilize the samel diaphragm-pin s both for receiving 'and alsofor reproducing the speech is shown in Figs. 4,'5,'and6. The said pin, which is shown separately on an enlarged scale in Fig. 6, is formed as a bifurcated pin, the upper part serving for'attaching-the pin tothe diaphragm. The pin .s is 4so shaped that one end, s2, formsa rounded point and is therefore suitable for reproducing speech, while the other end, s3, is formed as a graver of a suitable form for impressing the conversation on the phonograph-cylinder. According to requirements this. diaphragmpin may be brought into the position for receiving or giving o a conversation by means of the following arrangement: It is fixed by its upper part by means of a U -shaped bridgepiece s', held by means of two fasteningpieces l onto the glass diaphragm, vwhich'is clamped onto thebottomof the diaphragmbox 'm between two india-rubber rings m2 m3. In the position for reproducing speech shown in Fig. 4 the diaphragm-pin has its rounded point s2 resting on the phonograph-cylinder w. By means of the arrangement shown in Figs. 3 to 5 the pin may be'brought, as desired, into the reproducing or the recording position. In order that the otherlls, s3, of the pin may be brought into contact with the phonograph-roller for the purpose of recording a speech, the diaphragm-box im, is not directly attached to'the hinged part 'r4 of the IOO sound-tube, but to a tube or spindle T5, which is loosely movable within the socket or tube r4 on the same and projects from the latter at the top. The common axis xx of these two tubes is inclined at a given angle a from the vertical axis 7/ y of the diaphragm-box and the diaphragm-pin. The movable tube 9'5 is prevented from falling out of the sockettube 9"" by means of a pin-u, which projects at both sides at the uppef'end o and engages in a tiny groove formed on the upper edge of the socket-tube r4. By this means the proper position of the movable tube T5, diaphragmbox m, and diaphragm-pin s is determined. Vhen the pin is to be brought into the receiving or recording position7 it is only nec# ossary to turn the movable tube 7'5 within the socket-tube r4 to one hundred and eighty degrees, so that the index-pin fr again rests in the slot or groove. By this means the axis q/ 1/ of the diaphragm-box comes intol the position shown in Fig. 5, in which it, together with the diaphragm-pin s, ineloses an angle, such as 2a'. Simultaneously the end s3 of the diapliragn1-pin which serves for recording speech comes in contact with the phonographcylinder and in consequence of its inclined position assumes a suitable position for recording the speech or sound. The movable tube r", which is revoluble in the socket-tube r4, may, if necessary, be provided with two side slots lying diametrically opposite one another in order to allow the sound-waves diaphragm at each of the two positions.

By turning the diaphragm-tube one hundred and eighty degrees, as above pointed out, the point s2 of the diaphragm-pin is brought in contact with the phonograph-cylinder and into a position where its axis and the axis of the-soundtubes r1 T5 correspond. It is then in a proper position for reproducing.

In order to regulate the sound when reproducing speech, the horizontal part r2 of the sound-tube, as shown in Fig. 3, is arranged telescopically extensible in the tube a", so that the course which the sound-waves describe within the sound-tube may be increased or diminished. In order to exactly regulate this, a spring f is arranged within the tube-sections o" and lr2, which spring tends to force apart the two sections, and a screwed nut b is placed on a threaded bolt ZJ, which runs right through the tube-sections o" r2, whereby the latter may be telescopically adjusted against one another' by simply turning the said nut. The tube Wis provided with a slot corresponding with the end of the tube r, so

Shanks substantially parallel to the axis of the diaphragm and the other of its said Shanks disposed with respect to the said diaphragm at an angle substantially equal to double the angle of inclination between the axis of the diaphragm and the axis upon which the said diaphragm is carried.

2. In a phonograph, the combination of a diaphragm, or spindle carrying the said diaphragm and inclined with respect to the dia- Iphragm and to the true axis thereof and a doublcpointed stylus adapted for recording and reproducing carried by the diaphragm and in such relation thereto that upon rotating the diaphragm upon its spindle, one point may be shifted away from contact with the phonograph-cylinder and the other point brought into contact with the phonographcylinder, substantially as described and for the purposes set forth.

3. In an acousticapparatus,the combination of a plurality of'cylindrical sound-tubes r2?" which telescope one within the other and are arranged axially with respect to each other, a spring fand regulating-nut L for the purpose of effecting a shifting of the sound-tubes,
